For gyms

We are looking for our first partner gym.

Tensio is an app from Wildau, Germany, that helps people keep up their training beyond the first few weeks. Rather than finalising our offering for gyms at a desk, we want to develop it together with a business that knows day-to-day life on the gym floor.

We will get in touch personally and are happy to visit you. If you would prefer a fixed appointment straight away, you can also book a 20-minute video call directly (the booking page is in German). A conversation places you under no obligation.

Members who keep coming after the first few weeks

A goal the app verifies itself

Your members set their own goal, such as training three times a week. The app recognises the visit via a check-in at your gym’s location, without anyone having to report anything manually, and the sessions kept build a streak that members are reluctant to break.

A report in aggregate figures

Once a month, you learn how many of your members are taking part and how regularly they train. We do not pass on any personal data, you only see totals.

In preparation

Open around the clock, even without staff at the desk

Many gyms in rural areas struggle to find staff for late hours and weekends. For them, we are preparing an access solution that we would like to build together with the first gym that wants to use it.

  • The door opens via the app. Members show a QR code in the app at the entrance, and the door only opens for active memberships.
  • Occupancy is visible in advance. The app shows how many members are currently checked in, so that busy hours can be avoided.
  • We take care of installation. Fitting at the door is carried out by an electrician we work with.

This is not yet a finished product. Which door, which membership management system and which processes are needed, we will clarify with you on site, and only then decide what is built. In this way, the solution adapts to your gym and not the other way round.

Before you ask

What operators usually want to know first

What does it cost?

We discuss the terms for the first partner gym in a conversation and put them in writing before the pilot begins. Your members incur no costs through your gym.

Do I have to change my membership management software?

No. We look at the software you use today and adapt to it. Especially for the access solution, this is the first question we clarify with you, as the door needs to know whose membership is active.

Which phones does it run on?

Tensio is available for Android and, since November 2026, also for iPhone. How the app works with your door is something we will build together with you in the pilot.

Which of my members’ data will you see?

For the report, only aggregate figures. Who trained when remains in the member’s app and is not transmitted to you in a personally identifiable form. Further details can be found in our privacy policy (in German).

Who is behind it?

Two founders from Wildau near Berlin, Maurice Baugan and Anton Sakovich. We support the pilot personally and, where possible, will also come to your gym. You can find more about us on the About us page.

Is this a fit for your gym?

Send us a short message with the name of your gym and how best to reach you. We will reply even if the timing is not right. An email to Team@trytensio.com reaches us just as well.
